A4650 – AUTOMATIC STARTER FOR SYNCHRONOUS MOTORS

The A4650 trainer is an Automatic Synchronous Motor Starter for small to medium power motors. The unit is housed in a sturdy metallic cabinet for laboratory desk top use. Clear silk-screen printing indicates the various front panel features. Overload protection is included for safe operation of the trainer. Unless otherwise specified the unit is delivered pre-set as follows: AC mains voltage 3x380 to 3x415V with neutral, 50Hz Phase current limitation adjustable in the range of 0.63 to 1A This allows use with motors to approx. 600W

The A4650 operates by monitoring the rotation speed of the motor during the launching phase. This is done by an electronic circuit which detects the frequency of the EMF induced in the rotor winding. The frequency gradually tends to drop as the motor accelerates. A trigger circuit with adjustable threshold switches the motor to synchronous operation when this frequency lowers below the pre-set value. The A4650 is supplied with instruction manual.
